PALYNOMORPH BIOSTRATIGRAPHY OF THE SUBSURFACE DEVONIAN ROCKS, GHAZALAT BASIN, WEST QATTARA DEPRESSION, EGYPT
Bibliographic record
Abstract
Well–preserved palynomorphs dominated by miospores and subordinate acritarchs and chitinozoansare recovered from some cuttings of Ie 11 - 2 borehole drilled in the Ghazalat Basin in the west of Qattaradepression, Egypt . A total of 36 species of palynomorphs (25species of spores, 8 species of acritarchs and3 chitinozoan species) are identified. The palynological investigation of the studied stratigraphic intervalenabled the recognition of three informal zones ranging in age from Lochkovian to Emsian. Most of thepalynomorph taxa encountered are closely comparable with coeval assemblages recorded from NorthAfrica, Saudi Arabia, Western Europe and Canada, indicating the close relationship of the present area toother parts of the western Gondwana and southern Euramerican provinces during that time interval.Frequent representation of marine taxa (acritarchs and chitinozoans) together with associated sporesindicate near-shore marine depositional environment for the Lower and Middle Devonian (ZeitounFormation) deposits in north Western Desert region of Egypt.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
